    Stair-case artifact while playing video with hardware decoding enabled on Skylake

    medwatt

      I have a Thinkpad that came with i7-6700HQ CPU. I wanted to take advantage of the hardware decoding feature on skylake. I use PotPlayer as my primary video player to play videos. Whenever I use software decoding, videos play without any visual artifact. If I turn on hardware decoding, I start seeing a staircase as can be seen on the image below. Is this a driver issue? Can anyone confirm it?

       

      Some info on the video I was playing:
